SHlNGLE-MACHINE,

SPECIFICATION forming part of Letters Patent N0. 759,867, dated May 1'7, 1904.

Application filed April 27, 1903.

To all whom it may concern:

Be it known that I, ALBERT B. OUMMINS, a citizen of the United States, residing at Eureka, in the county of Humboldt and State of California, have invented certain new and useful Improvements in Shingle-Machines, of which the'following is a specification.

My invention relates to improvements in machines for cutting or shaping shingles, the object of my invention being to provide a machine of this character in which the shingles to be so cut or shaped may be segregated one at a time or in any desired uniform number at a time from the feed-supply, in which they may be securely and firmly held in position while being acted upon by the cutter, and in which they may be accurately and rapidly fed to and removed from the cutter.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved shingle-machine, certain parts being broken away. Fig. 2 is a front view of the machine. Fig. 3 is a detail perspective view of the cutter. Fig. 4: is detail perspective view of the pull-back. Fig. 5 is a longitudinal horizontal sectional view through the hopper, showing the clamping device in plan. .Fig. 6 is a longitudinal vertical section of the feed device.

Referring to the drawings, 1 represents the main frame of the machine, having extending therethrough a counter-shaft 2, said shaft having at one extremity thereof a belt-wheel 3, adapted to be driven from any suitable source of power. At the opposite end of the counter-shaft is secured a sprocket-wheel 4, connected by a sprocket chain 5 with a sprocket-wheel 6 upon a shaft 7, mounted in an extension 8 of the frame of the device, said shaft 7 carrying thereon a large sprocketwheel 9 for the conveyor-chain 10, which runs around an idle wheel in a groove 11 in a chute 22, carried by said extension 8 and beneath the hopper 12, which contains the shingles fed to the machine. Said chain carries projec Serial MAM i46- (No model.)

tions or lugs 13, which in the movement of the chain engage the rear ends of the shingles and feed them from the hopper to the shingle retainer or holder adjacent to the cutting mechanism. Said shingle-hopper 12 is in the nature of a box or chamber having an opening in the lower portion of the front side thereof, through which the shingles can pass, and having a sliding door 14, which is pulled down by a spring 15, secured to lugs 16 on said door and on the front side of the hopper. Said door is opened or forced upwardly against the force of said spring by a shingle when it is pushed forward toward the shingle retainer, the object of this door being to prevent the remaining shingles from being forced out before the lowest has entirely left the hopper. It will be understood that the ing or projection 13 of the chain is sufliciently high to engage the rear edges of the desired number of shingles. Thus if one shingle at a time is to be out then the height of the lug will be equal to the greatest thicknessof a single shingle. If two or three shingles are to be cut in a single operation, then the height of the lug will be equal to the thickness of two or three shingles at their rear ends.

In order to prevent more than the desired number of shingles from being removed at one time, there is provided a clutch mechanism comprising'two gripping-jaws 17, carried on the ends of arms 18 of levers pivoted at.. 19 upon the extenslon 8, sald levers having this time said shingles have been held up by said jaws, which extend upwardly as well as outwardly from the parallel portions of the arms 18, so as to grip the edges of the shingles at a point above the lowest shingle or group of shingles. They now, however, drop to the bottom of the hopper. After the shingles have so dropped the lug 13 comes along and impinges against the rear edge of the lowest shingle, (or the lowest two or three, as the case may be) and carries said shingle along with it, the jaws 17 in the meantime having closed upon the other shingles under the action of the spring 21, the lug having left the narrow path between the parallel portions of the arms 20. Thus only the shingle engaged by the lug is advanced and carried out of the hopper. After the shingle has been carried from the feed-hopper and has been propelled down the chute by means of the lug13 it is projected into one of a series of compartments23 of a rotary wheel or cylinder 24. These compartments are sector-shaped, being bounded by the parallel circular walls or plates 25 of the wheel or cylinder and by radial or diverging Walls or partitions 26 between said parallel walls and are open only at the periphery, where the shinges enter. At their inner ends said sector-shaped compartments are bounded by the hub of the wheel 24 and at. such a distance from the peripheries of the Walls 25 that the shingles projected into said compartments are arrested by said hub, so that their outer end extends beyond said wall 25 only sufficiently far to permit said end to be cut or shaped. Against the-front or leading Wall of said compartment rests the middle portion of a U-shaped clamp 27, the sides 28 of which extend over the outside of the walls of the wheel or cylinder and are pivoted in said walls at points near the center thereof, as shown. These clamps are normally drawn forward against said front walls by means of springs 29; but as the shingle arrives at the point where it is to be out said clamp is drawn back against the shingle to clamp the same by means of a pull-back 30, comprising arms 31,extending from a rock-shaft 32 and-drawn down by means of coiled springs 33. Said arms have forwardly-extending fingers 34, which are adapted to engage the sides of said yokes and pull the yokes against the rear wall, thereby clamping the shingle against said wall while passing the cutter. Said cutter comprises cutting-blades 35, mounted upon a head 36' upon a shaft 37,driven by a pulley 38 from any suitable source of power. The speed of the cutter is great compared with that of the rotating wheel 24, so that the cutting takes place While the shingle is advanced through a very small distance, and on account of the oblique inward direction of the fingers 34 said fingers are gradually pushed out as the wheel advances, thereby releasing the Ushaped clamp, so that the shingle is now no longer held thereby. When the shingle arrives at a lower position in the rotation of the wheel, it is projected from the compartment,and the shingles thus projected may be collected'from time to time.

I elaim' 1. In an apparatus of the character described, the combination of a cutter, a rotat ing cylinder comprising parallel side plates, and radial partitions between the side plates dividing the space between the plates into sector-like compartments, and means for automatieallyfeeding the shingles into said compartments, substantially as described.

2. In an apparatus of the character described, the combination of a rotating cylinder comprising parallel side plates, radial partitions between the side plates dividing the space between the plates into sector-like compartments, said cylinder being provided also with means for arresting the end of a shingle projected into the compartment at such a point that the part to be operated by the cutter projects beyond the compartment, a cutter wholly outside. the cylinder, and means for automatically feeding the shingles into said compartments, substantially as described.

3. In an apparatus of the. character described, the combination of arotating cylinder comprising parallel side plates and radial partitions between the side plates dividing the space between the plates into sector-like compartments, a normally inoperative clamping device in each compartment for holding the shingle against the partition on one side thereof, a cutter, and means brought into operative connection with the clamping devices insuccession as they pass the cutterto cause them to clamp the shingles, substantially as described.

4. In an apparatus of the character described, the combination of acutter, arotating cylinder having radial supports for the shingles, pivoted U-shaped clamping devices for clamping the shingles against said supports, springs for normally holding said clamping devices out of engagement with the shingles; and means for engaging said clamping devices to cause the same to hold the shingles when passing the cutter, substantially as described.

5. In a device of the character described, the combination with the cutter, the means for carrying the'shingles past the cutter, and the hopper, of the gripping device for gripping the upper shingles comprising the pivoted levers having the arms first converging and then extending substantially parallel with each other and. provided with terminal jaws engaging the sides of the shingles, the spring for drawing said arms together, and the chain having lugs which pass between and in contact with the convergent portions of said arms and cause the same to diverge to release the shingles, substantially as described.

6. In a device of the character described, in means for feeding the shingles, the endless chain having links rising above said chain, in

I separate the jaws sufficiently to release the shingles when passing therebetween, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ALBERT B. CUMMINS.
